1 Submit your site to web directories
2 Submit to social bookmarking sites
3 SEO
4 Put your link on Myspace
5 Forum Signature
6 Article Submission,link your site on the Biography part.

Those are some very good tips.  The tough part comes when you have done a majority of the above, but still come up short in traffic.  

In that case, how long would it be appropriate to wait for the changes to take place before trying something new? How long does it take to notice a change in traffic data? Obviously, things don't happen overnight.

web directories dont count these days i have heard because links are sold there...thats what " The official google blog says" and "Google discourages link sales for better pagerank"

So, i would suggest, create a honest site and do onpage SEO without abuse and you will eventually get traffic!

Thats what i feel.
Cheers!

Yes some web directories are devalued. This is just because the web directories are popping out like mushrooms all over the internet.

To get one way backlinks blog reviews and article submissions would help better then submitting it to thousands of directories.

I wrote one article on difference between a web directory and a link farm will find it in my HDD and post it in tips section.

Thanks.
